What other use do they have? A floor mob or something?
They are, and always will be weapons.... Your ignorance is amazing..
I'm going out on a limb here, and say how people like you are the prime example why we need gun regulation that includes individual evaluation of the gun owner.
You are amongst those people I feel most uncomfortable with to own a gun. Your ignorance, and/or lack of comprehension disqualifies you for being a responsible gun owner.
